Multi port support

[starsareintherose]

If my port 3000 is occupied, how can I run this program?

[mohit038-zz]

You can define PORT as an environment variable in the .env file.

[starsareintherose]

such as PORT=3360 ?

[starsareintherose]

my .env is here

[root@archlinux JabRefOnline]# cat .env
DATABASE_URL="postgresql://root:passwd@localhost:5432/jabref?schema=public"
PORT=3380

but it shows

[root@archlinux JabRefOnline]# yarn dev
yarn run v1.22.11
$ nuxt

You need to start redis as well

[starsareintherose]

I have used systemctl to start and enable redis, but it still shows that

in the package json I see that it uses a docker container to start redis on port 6300

JabRefOnline/package.json

Line 26 in 08fd8d5

"docker:redis": "docker run -d --rm --name JabRefRedis -p 6380:6379 redis --requirepass jabref",

[starsareintherose]

That's so sad, I must need to install docker

[tobiasdiez]

You don't need to use docker, just make sure redis is listening on port 6380. I've clarified this point in the readme.

[starsareintherose]

Things seem okay, but the web shows ERR_CONNECTION_REFUSED

Did you init the postgres database? That was my problem as well.
Run yarn prisma:migrate:dev to initialize the database. You may also want to use yarn prisma:seed to fill the database with some initial test data.

Then run and log in using the Test-User provided in the readme:
http://localhost:/user/login

[starsareintherose]

I follow the readme, actually.

yarn install
yarn prisma:migrate:dev
yarn dev

[Siedlerchr]

run yarn prisma:seed to fill the database

[starsareintherose]

same error exsit, but a little strange, I can curl it on VPS via localhost, but fail on my PC of the domain via IP or Domain.

[tobiasdiez]

I don't really understand your last comment. It seems that the development server runs successfully on localhost. Not sure why you would expect it to run on your domain. Did you try to run jabref online on your server as well?

[Siedlerchr]

Did you add an ufw rule to allow for that port?
Edit// Also try HOST: 0.0.0.0 in your env

[starsareintherose]

Right, I added. It's running on my VPS.
